The default value for the host argument is the localhost.
The display for each route table entry shows the multicast group and source addresses, the (virtual) interface on which packets arrive, the number of seconds until the entry times out, the received packet and byte counts, the number of RPF fails, and the protocol. A sample use and output might be:
% mstat sydney.eecs.umich.edu IP Multicast Route Table for sydney.eecs.umich.edu Mcast-group Origin-Subnet InIf UpTime ExpTm Pkts Bytes RpfFl Proto NTP.MCAST.NET 128.4.1.1/32 1 156 375 1 96 0 dvmrp NTP.MCAST.NET 128.232.0.56/32 1 466 74 1 96 0 dvmrp IETF-2-AUDIO. 128.119.40.58/32 1 463 30 1 46 0 dvmrp 224.1.1.94 138.96.24.77/32 1 1665 21 312 38376 0 dvmrp 224.2.0.1 13.2.117.114/32 1 166 180 1 59 0 dvmrp 224.2.0.1 16.1.0.24/32 1 340 210 1 58 0 dvmrp ...
The display for each group shows the multicast group address, the mode (dense or sparse), number of rendezvous points (RPs), and the number of seconds until this router will send RP-reachable messages. If the host does not use PIM, the table will be empty. A sample use and output might be:
% mstat -G maingate.princeton.edu PIM Group Table for maingate.Princeton.EDU Group-Address Mode RPs Tmr NTP.MCAST.NET dense 0 0 IETF-2-AUDIO.MCAS dense 0 0 SUN-RPC.MCAST.NET dense 0 0 224.1.1.94 dense 0 0 224.2.0.1 dense 0 0 ...
The display for each PIM interface shows the interface number, local IP address, mode (dense or sparse), the designated router for the interface, and the frequency in seconds of router-query messages. A sample use and output might be:
% mstat -I maingate.princeton.edu PIM Interface Table for maingate.Princeton.EDU If Address Mode DRouter Ttl Int 3 128.112.120/22 dense 128.112.120.1 0 30 4 128.112.224/22 dense 128.112.224.1 0 30 6 128.112.200/22 dense 128.112.200.200 0 30 7 128.112.232/22 dense 128.112.232.1 0 30 9 maingate.Princeton dense 0.0.0.0 64 30
The display for each PIM neighbor shows the interface number, seconds since the router (last) became a neighbor, seconds until this entry times out, active PIM mode (dense or sparse) of the neighbor, and the neighbor address. A sample use and output might be:
% mstat -P maingate.princeton.edu PIM Neighbor Table for maingate.Princeton.EDU If UpTime ExpTm Mode Neighbor 6 0 85 dense csgate.Princeton.EDU
The display for each scoped boundary shows the interface number and administratively scoped boundary address. A sample use and output might be:
% mstat -b sydney.eecs.umich.edu Boundary Table for sydney.eecs.umich.edu Vif Boundary Address 1 239.2/16
The display shows the (virtual) interface number, seconds since the router (last) became a neighbor, seconds left before timing out, the generation ID and version number of the neighbor, and the neighbor address. A sample use and output might be:
% mstat -d sydney.eecs.umich.edu DVMRP Neighbor Table for sydney.eecs.umich.edu Vif UpTime ExpTm GenId Version Neighbor 1 1637 136 796725035 3.3 videosrv2.engin.umich.edu
The display shows the multicast group address, the interface number, whether the local system is a member of the group address on that interface, the number of seconds since this row was created, the number of seconds left until it expires, and the last system reporting itself a member. A sample use and output might be:
% mstat -g sydney.eecs.umich.edu IGMP Group Table for sydney.eecs.umich.edu Group-Address Vif Self UpTime Tmr Member 224.2.127.255 0 true 1498 164 sydney.eecs.umich.edu 224.2.212.225 0 false 1503 177 grinch.eecs.umich.edu
The display shows the interface number, local and remote addresses of the interface, the metric and threshold, and the type and current state. A sample use and output might be:
% mstat -i sydney.eecs.umich.edu DVMRP Virtual Interface Table for sydney.eecs.umich.edu Vif Local-Address Met Thr Type State Remote-Address 0 141.212.99.117 1 1 querier up 141.212.98/23 1 141.212.99.117 1 1 tunnel up videosrv2.engin.umich.edu 2 141.212.99.117 1 1 tunnel down conn1054-classroom1.engin.umich.edu
The display shows the origin, incoming Vif, distance to origin, seconds until timeout, and upstream neighbor. A sample use and output might be:
% mstat -r sydney.eecs.umich.edu DVMRP Route Table for sydney.eecs.umich.edu Origin-Subnet IVif Met Tmr UpstreamNeighbor 13.0.32/22 1 11 173 videosrv2.engin.umich.edu 13.1.100/22 1 9 173 videosrv2.engin.umich.edu 13.1.108/22 1 10 173 videosrv2.engin.umich.edu 13.1.136/22 1 10 173 videosrv2.engin.umich.edu ...
The display shows the origin, outgoing (virtual) interface, and state (leaf or branch). If status is leaf, then a multicast datagram from that origin will be forwarded on that outgoing vif only if there are members of the destination group on that leaf. A sample use and output might be:
% mstat -t sydney.eecs.umich.edu DVMRP Route Next Hop Table for sydney.eecs.umich.edu Origin-Subnet OVif State 13.0.32/22 0 leaf 13.0.32/22 2 leaf 13.1.100/22 0 leaf 13.1.100/22 2 leaf 13.1.108/22 0 leaf 13.1.108/22 2 leaf ...
The display shows the virtual interface number, remote address, incoming and outgoing packet and byte counts, the rate limit, and the interface type and current state. A sample use and output might be:
